MUSMYS A75 Pure Class A 120W*2 4ohm HIFI Power Amplifier 12 Field Effect Power Transistors PK AccuphaseA-75

MUSMYS
CLASS-A  STEREO  POWER  AMPLIFIER
A-75
 ● Pure A-class output, 120W4Q × 2 stereo sound
 ● The output uses 12 field-effect power transistors per channel, which can drive impedance as low as 1 Ω.
 ● The input adopts an exclusive self-developed fully balanced low-noise module, which can greatly broaden the frequency response of music, improve sound clarity and intensity.
The voltage amplification part adopts two parallel connections to reduce input noise and improve dynamic range.
 ● Adopting direct current stabilization technology to ensure stable operation of the power amplifier.
 ● Added mains (220V) isolation technology to effectively isolate DC components from entering the transformer.

A75 amplifier is a registered independent brand independently developed and produced by MUSMYS factory. It is designed and debugged by the R&D team led by Yayu. Yayu has decades of rich experience in designing, debugging, and comparing sound in the audio industry. A good amplifier is not judged by how luxurious or expensive the materials are, but mainly by the skills of the design engineer. Even with ordinary materials, a good project can design an excellent HiFi amplifier. This amplifier is the essence of the original circuit of Japanese Golden Throat A75. After all, this 100000 yuan Golden Throat circuit is excellent, and it is also famous in the audio industry. The Miaosi A75 amplifier, due to the use of field-effect transistor amplification tubes, has a very bold sound and is positioned as a high-end amplifier. Its excellent performance, atmospheric appearance, reasonable layout, and high temperature components will definitely become your good companion in life, allowing beautiful music to accompany you at all times and allowing you to enjoy life and happy every day.



The "A-75" includes an upgraded version of the "MCS+circuit" with an initial slow charging amplifier circuit equipped with "MCS", an improved multi-level parallel circuit design, and a current feedback design to ensure linear response at each level. The amplification unit circuit is connected in parallel to reduce noise, and a DC stabilized power supply is installed in the driving section and MCS+circuit to improve the SN ratio and enhance the purity of the sound. The high-efficiency large transformer is housed in a metal cover and equipped with a "super large pond" filtering group to provide sufficient and stable power supply. The amplifier section adopts a fully balanced amplification circuit design, with 12 high-power field-effect transistors used for amplification output per channel, achieving high-quality high driving force and providing true power amplification outputs of pure Class A 60W × 2 (8Q), 120W × 2 (4Q), 240W × 2 (2Q), and 480W × 2 (1Q). Provide powerful power output and super strong driving capability.
